electrical supply must comply with IEE wiring regulations and any local regulations which may apply for fixed wiring to a stationary appliance.
• Any system connected to the boiler must not have a separate electrical supply.
WATER SUPPLY:
The following are general requirements and if necessary the advice of the local water company should be sought before fitting the appliance.
•The appliance cold water supply should be the first connection off the water main where possible.
Water Mains Pressure:
Minimum dynamic mains water pressure for optimum performance.
12/18kW |
18/25kW |
25/32kW |
|
|
|
1.5 bar |
1.2 bar |
0.9 bar |
|
|
|
•Maximum mains fed water pressure 10 bar. If necessary, fit a pressure reducing valve.
IMPORTANT: Non-return, back flow prevention devices (including those associated with water meters) fitted to the mains water supply can cause a pressure build up which could damage the boiler and other household appliances.
•Where the water main supply has a nonreturn, back flow prevention valve fitted, a mini expansion vessel (A) must be connected to the mains water inlet pipe (B) between the non-return valve (C) and the boiler (D) as shown opposite.
Use in hard water areas:
Normally there is no need for water treatment to prevent scale formation as the maximum temperature of the heat exchanger is limited by the control circuit.
In areas where the temporary water hardness exceeds 200ppm, consideration may need to be given to the fitting of a scale prevention device. In such circumstances, the advice of the local water authority should be sought.

The table and illustration above is a guide only and does not in any way override the deaerator manufacturers instructions.
OIL SUPPLY
This appliance is suitable for kerosene (28 second oil) only, no other fuel must be used.
OIL SUPPLY:
•Plastic or steel tanks should be installed to BS 5410. A steel tank should conform to BS 799: part 5 and have a slope of 1 in 24
away from the outlet valve with a sludge cock at its lower end.
•Do not use galvanised steel tanks or pipework for the oil supply system.
•Do not use soldered joints on the oil supply pipework.
a) Single pipe gravity feed system:
The oil storage tank (A) must be positioned so that the oil level does not exceed 4 metres above the level of the burner oil pump (J) and in addition the oil level must be at least 300mm above the oil pump (J). Where the maximum oil level in the oil storage tank exceeds 4 metres, a head breaking device must be installed between the tank (A) and the burner oil pump (J).
b)Double pipe sub-gravity feed system:
Maximum suction height 3.5 metres. Non-return valves must be fitted to the inlet and return oil line between the oil pump (J) and oil storage tank (A).
c)Single pipe suction lift with de-aerator
Maximum suction height 3.5 metres. The oil tank (A) must be positioned below the oil pump
(J). Create an inlet and return loop between the de-aerator (M) and oil pump (J).
A non-return valve must be incorporated within the de-aerator or fitted to the oil line between the oil storage tank (A) and the de-aerator (M).
A top feed oil tank fitted with a de-aerator using an internal non-return valve should have any non-return valves fitted in the base of the tank to the suction line removed to assist purging air from the oil line.
Pipework
Use copper pipe of the correct diameter according to the information shown opposite. Use flexible hoses to connect to the oil pump (J).
Lay the oil supply pipe (H) as straight and level as possible to avoid air pockets and unnecessary friction losses. Route away from the boiler access door or other hot surfaces.
Install a manual isolating valve (B) to the oil supply pipe (H), as close to the oil storage tank (A) as possible.
Fit an oil strainer and water seperator (C) to the oil supply pipe, near the oil storage tank. Fit an additional oil filter (N, 16µm max filtration size) close to the boiler, but not inside the boiler casing.
Fit a fire valve in accordance with BS 5410. The fire valve (D) must be fitted externally at least 1 metre from the appliance with the fire valve sensor (F) located within the appliance case.
A capillary type valve provides a neat and simple installation. Alternatively, a fusible link or electrical system may be used.
Under no circumstances should a combination isolating/fire valve be used as the sole fire protection device.

CONDENSATE &
PRESSURE RELIEF PIPEWORK
CONDENSATE PIPEWORK:
•All national and, where appropriate, local regulations for the discharge and neutralisation of condensate should be followed.
•The condensate pipe must be a minimum of 21.5mmØ polypropylene pipe.
•The condensate pipework must fall at least 50mm per metre towards the outlet and should take the shortest practicable route and not exceed 3 metres outside the building. If a run greater than 3m is required, 32mmØ polypropylene pipe must be used.
•The pipework must follow one of the options shown opposite:
a - Internal waste drainage system b - Soil/vent stack
c - External drainage system
d - External condensate absorption point
•Condensate pipework must not be connected to rainwater downpipes.
•Use waterproof pipe insulation in exposed positions and for external pipework
IMPORTANT: Condensate pipework must not leak and the condensate trap must be filled with water before the boiler is started to prevent the possibility of potentially harmful flue products escaping via the condensate route.
A - Condensate from the boiler condensate trap (supplied) which has a 75mm minimum water seal.
B - Sink.
C - 21.5mm Ø polypropylene condensate pipe.
D - Gully.
E - Internal soil and vent stack.
F - 300mm x 100mm Ø sealed plastic tube.
G - Ground level.
H - Drainage holes 50mm from base of tube (12mm Ø at 25mm centres) facing away from building.
I - Limestone chippings.
PRESSURE RELIEF PIPEWORK:
IMPORTANT: The pressure relief valve is a safety device for the boiler and if activated may discharge boiling water or steam through the relief valve drain pipe.
Care should be taken when siting the outlet pipe so that it does not cause an obstruction or discharge above a window, entrance or other public access where it could cause a hazard.
•The pressure relief drain pipe (K) should be at least 15mm diameter copper pipe and run
downwards away from the boiler and discharge away from any electrics or other hazard, preferably to an external drain or soakaway.
•Pipe (K) should be finished with a partial bend, near the outlet to face the external boiler casing (as shown) to help prevent freezing.

FLUE TERMINAL POSITIONS
• |
Flue terminals must be positioned to avoid |
|
|
|
combustion products entering into buildings. |
|
|
• |
The flue must be fitted and terminated in |
|
|
|
accordance with the recommendations of |
|
|
|
BS5410. |
|
|
• |
The flue must not cause an obstruction. |
|
|
• |
Discharge from the flue outlet must not be a |
|
|
|
nuisance. |
|
|
• |
Flue gases have a tendency to plume and in |
|
|
|
certain weather conditions a white plume of |
|
|
|
condensation will be discharged from the flue |
|
|
|
outlet which could be regarded as a |
|
|
|
nuisance, for example, near security lighting. |
|
|
• |
There should be no restriction preventing the |
-PRE |

|
|
|
|
|
terminal. |
|
|
• |
The air inlet/outlet duct and the terminal of |
|
|
|
the boiler must not be closer than 25mm to |
|
|
|
any combustible material. Detailed |
|
|
|
recommendations on protection of |
|
|
|
combustible materials are given in BS 5410:1 |
|
|
• |
A protective terminal guard must be fitted if |
|
|
|
the terminal is 2m or less above a surface |

B(H) Balanced Horizontal flue
1 An opening means an openable element, such as an openable window, or a permanent opening such as a permanently open air vent.
Notwithstanding the dimensions above, a terminal should be at least 300mm from combustible material, e.g. a window frame.
2A way of providing protection of combustible material would be to fit a heat shield at least 750mm wide.
